The alternative is to remove it from testing.

The changes between 1.20 and 1.21 are minimal, those can't be the
reason for the failure. Probably either changes in perl or libc
broke it.

I expect 1.20 fails in the same way at least on sid, and probably
in testing too.

I've made some progress on it fwiw, and it seems to be something with
two print statements in different modules getting the same opcode address
on the perl side, therefore hashing down to a same hash key and getting
counted as one. Will update the upstream bug when I've got.to the bottom
of it.
